Few possibilities: This can be caused by several issues. Chemical and hair products can cause irritation of the scalp. You can also just have dry scalp, atopic dermatitis(eczema), allergic reaction, and sensitive skin. There are several shamppos that can help with this. The key is to remove the offending agent(s) if they can be identified.
